Remember that the formula for the surface area of a sphere is

. Substitute the given surface area to solve:

. Divide by 4 on both sides:

. Divide by pi on both sides:

. Square root on both sides to find the radius:
It would be 6x5 squared-5x4+8
150-20+8=138

Answer:
−4x+y+6z
Step-by-step explanation:
Let's simplify step-by-step.
2x+5y−z−6x−4y+7z
=2x+5y+−z+−6x+−4y+7z
Combine Like Terms:
=2x+5y+−z+−6x+−4y+7z
=(2x+−6x)+(5y+−4y)+(−z+7z)
=−4x+y+6z
